ld.so fc4 kernel 2.6.16-1.2111 behavior comments

[Skunk Worx]

asking for my tech lead...

he claims the dynamic loading changed in fedora sometime in the last 
several months.

we have an application set with the usual bin,lib,include directories, 
and ld.so.conf entries to support the lib.

he did a toplevel 'make clean ; make' on our source tree, which wiped 
out the existing so's from our lib on the hard drive and replaced them 
with the latest.

then he started an app from our bin. he says the new symbols from the 
latest .sos were not present in dlsym calls. the old .so was still 
somehow being used.

according to him this is broken behavior...he says this should never 
happen if the disk file changes, and he runs ldconfig (as he did), 
whether an existing app still has chunks of the old .so mapped or not.

an init 6 cleared the problem (obviously)

just curious if anyone has comments ... or pointers to a commentary 
about the behavior...i will relay them and post back as necessary.


thanks,
John
